To all whom it may concer-n Be it known thatI, HENRY C. HERR, a

` citizen of the United Statesof America, re-

siding at Pittsburgh,in the county of Allegheny and State ofPennsylvania, have invented certain newk and useful Improvements inBarrel-Heading Machines, of which the following is a specification,vreference being rhad therein to the accompanying drawings. f

The invention relates to package heading machines and consists in theconstruction as hereinafter set forth. Y

In the drawings, Figure l is an elevation of the machine partly insection; Fig. .2 is an elevation viewed at right anglesto Fig. l; Fig. 3is a vertical central section through the nailing mechanism; Fig. 4f isa sectional plan view thereof; Fig. 5 is a plan of the nail yreleasingmechanism; Fig. 6 is a cross section through a portion of the assortingmechanism; and Fig. 7 is a horizontal section showing the operation ofthe flange rolling mechanism.

The improved machineis capable of being used for the heading of packagesof various constructions but as illustrated and specilically described,it is particularly designed for use in the heading of packages havingcylindrical'bodies formed of spiral wrappings of paper or similarmaterial. The heads are formed of wood and are provided with the usualcroze of barrel construction, butias the body is not provided with agroove the head is engaged with a chine-hoop formed of metal. This hoophas a V-shaped groove to fit the croze of the head and is of a sizecorresponding to the internal diameter of the body soas to be capable ofentering the end thereof. The hoop is also preferably provided with areturn bent flange which passes around the end of the cylindrical bodyand over the outer edge thereof, formi ing a metallic reinforcement.

The operations performed by the machine are first, the pressing of thehead and chinehoop into engagement with the end of the cylindrical body;second, the rolling down of the outer flange of the chine-hoop which isoriginally of the flaring form to permit the entrance of the end of thepaper body; third, the automatic nailing of the head, the

nails being distributed around the body and arranged to pass through thesame, the chine-hoop, and into the headv in' a radial direction. Theseoperations are performed by a mechanism, thedetail construction of whichis as follows: The frame of the machine is preferably formed of a bed A,standards B rising therefrom, and an annular top frame C moLmted-at-theupper ends of said standards. Centrally within this frame is a yertiealmovable plunger or work supporting table D which is reciprocated bysuitable mechanism such as a crank E and abutment F. The plunger isguided in slide-ways G on the standard, and the crank is mounted on ashaft H driven at slow speed through the medium ofthe step-down geartrain I from a `drive-shaft J, while theV clutch K and trip pedal Lcontrol the cycle of movement. The arrangement is such that during eachcycle Vthe plunger or work table D is raised from and lowered again byone complete l revolution of the crank.

package to be headed is work table D, the lower end engaging` thecircular guide D which properly centers the Work.L The upper end of thebody upon which the head and chine-hoop are placed, is in registrationwith an annular guide'M and an annular abutment N, these parts operat-Thebody of the placed upon the ing'during the rise of the plunger toforce the head and chine-hoop into-full engagement with the cylindricalbody. To provide for-slight inequality-in size, the plunger D isprovided with a yielding top plate D? resiliently supported on springsD3. This yielding connection is also employed for another importantfunction, that -is I to' provide a suitable interval of delayl betweenthe completion of engagement of the head with the body and the loweringof the Vwork in which ythe liange closing and nailing operations may beperformed. Thuswhile the movement of the crank and plunger is continuousthe movement imparted to the work is intermittent.

Flange .closing meczczm'sm.-As has been already described, thechine-hoop O is provided with a return bent flange O for fitting overthe end of the paper body and this flange is originally of aflaring-form 'to receive the end of the body 'and to guide it into fullengagement with the hoop. The flared flange is then closed down intocloseengagement with the body by the operation of presser rolls. Therolls P are distributed a'boutthe package body and are carried by arevoluble annular member which also constitutes an element in thenailing mechanism, to be hereinafter described. The member P issupported upon the annular member C and is provided with peripheral gearteeth P2 which are in mesh with the pinion P3 on the vertical shaft P4intermittently driven by a bevel pinion P5 engaging an interrupted bevelgear wheel PG on onev of the members of the gear train J. This mechanismwill impart an intermittent rotary movement to the annular member P andthe timing is such that the member P begins its rotation upon thecompletion of the full engagement of the head with the body andcontinues to rotate during the interval of delay caused by thecompression and eX- pansion of the spring D3. The member P then remainsstationary during the remainder of the cycle and while the work on theplunger is being lowered.

During the intermittent rotation of the member P the rolls P travelabout the liange of the chine-hoop and the distance traveled issufiicient to cause the rolling down of all portions of the flange.V Aspreferably constructed and as shown, the annular member P travels duringeach movement one third of a revolution and as there are siX rollsequally spaced the operations performed thereby are equivalent to twocomplete revolutions of a single roll. n their normal positions therolls `P are sufficiently withdrawn from the chine-hoop to provide anunobstructed path for the latter as it is forced upward against theabutment N. During the initial movement of the member P, the rolls arebrought into contact with the periphery'of the chine-hoop and are heldthere during the continued movement, this being accomplished by thefollowing construction: Q are rockable members pivotally attached at Qto the member P and extendingv inward therefrom. The rolls P arejournaled at the front ends of the members Q and the latter are normallyarranged at a slight angle to the radius of the member P being yieldablyheld in this position by springs Q2 which draw them against adjustablestops Q3. In this position the rolls areA withdrawn from contact withthe chine-hoop as has been already stated, but adjacent to the rolls arearranged yieldable stops Q4 which project from the stationary member Non which the abutment N is formed. The stops Q4 project outward from themember N into the path of movement of the rolls P during the rotarymovement of the member P and Jform a suiiicient obstacle to temporarilylarrest said roll and cause the arm Q to swing upon its pivot. Thismovement will continue until the arm Q bears against an adjustable stopQ5 on the opposite side thereof, after which the arm Q yand roll P arecompelled to rotate with the member P riding from the stop Q4 bypressing the latter inward against the tension of a spring QG. Theswinging movement of the arm Q will carry the roll P inward into contactwith the chine-hoop which is pressed against f the cylindrical body ofthe package and during the continued operation is rolled in firm contacttherewith. At the completion of the movement the springs Q4 will drawthe arms Q again against the stop Q3 withdrawing the rolls P fromcontact with the hopper.

Nail-ing mechanisch-The mechanism employed for nailing the heads to thebodies comprises first, mechanism for extracting the nails from anirregular mass in the hopper and arranging them in parallelism, second;means for periodically distributing the required number of nails intothe position for handling, and third; means for driving and pressing thenails radially inward. The first of these groups of mechanism or thenail assorting means, includes a hopper R the bottom plate of which isinclined and formed with a series of V-shaped grooves P. therein. rPhebottoms of the grooves are of suliicient width to receive the body ofthe nail, but too narrow to permit the head of the nail to entertherein.

R3 is a slide having V-shaped sheet metal flanges tting over theV-shaped ribs on the bed between the grooves R.

Pt* is the front plate of thehopper provided with depending V-shapedlugs R5 with the apex of each V cut away and' concaved suciently topermit the head of the nail to pass therebeneath. These lugs fill thegrooves R with the exception of the lower portion thereof, providingonly suiicient clearance for the movement of the V-shaped fingers R3.

R is a grooved guide having the slots or grooves alined with the groovesR, said guide extending in an inclined position from the hopper R.

R7 is a cross-head to which all of the fingers R3 are attached.

R8 are pitman rods connecting said crosshead R7 to cranks R9. Thus everytime the cranks R9 are rotated the fingers R3 are given theirreciprocatory movement, being pressed into and withdrawn from the hopperR. In this movement the nails lying in irregular arrangement within thehopper are agitated in such a manner that they will tend to arrangethemselves parallel to the direction of movement of the fingers with oneof the nails at the bottom of each groove R. In this position the nailis free to move endwise beneath the lugs R5 out from the hopper. Herethe head of the nail will engage 'a stop plate R10 and at the same timethe body of the nail will .pass into registration with the slot in theguide 'Re permitting it to drop while the head remains in engagementwith the guide and suspends the nail. The result is that the nails arearranged in parallelism being all suspended by their heads and beingfree to travel down the inclined guide to the lower end thereof. At thispoint there is arranged a laterally movable bar S provided with recessesS which register with the slots in the guide and are adaptedl to receivethe nail from each and to carry said nail laterally.

S2 are pockets in the guide R6 into which the nails are forced out ofengagement with the recess in the bar S upon the lateral movement ofsaid bar by the action of cams S3. The cams are formed by grooves in theunder face of a bar S4 arranged above the guide and the arrangement issuch that the nails which have thus far been suspended by their heads inthe guide R6 and inthe bar S, are forced into the recess S2 which is ofsuihcient size to permit the passage of the head, thereby allowing thenail to fall.

`With the mechanism just described, the nails are extracted from anirregular mass, are arranged in parallelism, and upon each operationofthe laterally shiftable bar Sa predetermined number of Ynails aredisengaged from the Vguide and are dropped. From this point the nailswhen liberated Vcan be distributed to the proper positions for nailing,but as it is necessary to arrange them radially with their headsextending outward reversing mechanism is provided by which the nails aredropped head downward. This reversing mechanismvcomprises a rotarymember T having pockets T preferably on opposite sides thereof and whichare periodically registered with the recess R2 from which the nailsaredropped. Thus upon each reciprocation of the bar S the nails droppedthereby are deposited in the pockets T, and upon the rotation of themember T, are carried into a reverse position, being held from"disengagement by a segmental guide T2. v

T3 is a gate arranged beneath T upon which the heads ofthe nails whenreversed temporarily rest.

T* are conduits beneath the gate T2 in registration with the nailpockets T, the arrangement being such that the gate T3 will be withdrawnto simultaneously dischargel all of the nails in their respectivepockets into the conduits, through which they pass by gravity in radialdirections to the nailing position. For driving the parts of themechanisms above described, beveled gear wheels U transmit rotary motionfrom the shaft P4 to horizontal shaft U, gears U2 on this shaftcommunicating movement to the cranks R". Motion is also transmittedvagainst the outer the member Y from the shaft Uthrough the medium ofintermeshing gears U3 to the rotary member serves to reciprocate saidbar which is returned by a spring UG. The gate T3 is actuated by a camVon the shaft U which positively moves it forwardinto a position forinterceptingfthe nails, while springs V effect a quick release upondisengagement with the. cam. As shown the cam V has a peripheral notchV2 therein with which a lug V3 on the gate is engaged when in itsretracted position, and a shoulder VL at one side of the notch V2governs the lug V3 in closing the gate.

Nail hinting mecmm'sm.-The nails when released by the gate T3 are movedby gravity through the conduits T4 which extend radially to a series ofpoints preferably equally spaced about the periphery of the packagehead. The nails in falling through the conduits will acquireconsiderable velocity, and to prevent recoilinv' when reaching the endof their course, a special construction is provided. rThis consists of apocketed member W preferably mounted upon the revoluble member P andhaving' an inclined deflecting face Vf. rThis pocket is registered withthe corresponding conduit T4 at the time ofV release by movement of thegate T3, and the nail traveling down the conduit, head foremost,-willstrike against the inclined shoulder lV and will be deilected downward.The pocket VT is so fashioned that the head of the nail is permitted topass downward through a slot TVE at the outer endr of the pocket, whilethe body of the nail passes through a slot of restricted width l/VS.This forms a shoulder VW* for engaging with the Vhead ofthe nail and anyrecoil occasioned by the striking of the head end of the pocket will beprevented by the shoulder VVJ which prevents inward movement of the nailbut permits it to drop downward through 'the slots W2 and VW. Beneaththe pocket W in its position of rest, is a radial slot X in the memberC, and alining with this slotis a nail driver X which has ananti-friction roll X2 engaging a cam slot in the under face'of therotary member P. The slot T3 is of a form to hold the driver X yat theoutward end of its movement during a part of the revolution of themember P and to impart an inward radial movement to said driver duringanother portion of the rotary movement of the member P. Every alternatedriver engages a similar portion of the cam slot X3, while theintermediate drivers engage a different portion of said slot, thearrangement being one to effect the simultaneousfmovement of one half ofthe drivers and alternately the simultaneous lmovement of thev otherhalf. This will divide up the work of driving the nails and decrease thepower required for the machine. The rotary member P is preferablycompletely housed in a cap member N2 which is secured to the annularmember C and has dependentv therefromV a flange N on which the abutmentN is formed. This fiange N also forms a journal for the rotary member Pwhich is provided with anti-friction rolls N4 engaging said fiange.

The construction being as described in operation, a supply of nails isdeposited in the hopper R, and after the assortment of a portion ofthese nails by the mechanism described, the machine is in condition foroperation. The workman first places the package body upon the table orplunger D centering it by engagement with the circular guide D. At thesame time the head with the chine-hoop in engagement there with isplaced at the top of the body with the lower edge of the hoop justentered into engagement. Motion is then imparted to the machine byactuating the tripping pedal L which throws in the clutch K andcommunicates motion from the shaft J through the gear train T to thecrank E, and through the abutment F to the plunger D. The plunger isthus raised, carrying up the package which is guided by the annularmember M into engagementwith the abutment N. Here further movement ofthe head and chine-hoop is prevented but the body continues to be forcedupward until in full engagement with the head. This occurs before thecranl has reached the upper limit of its movement and thus the plungercontinues to rise but is permitted to do so without injury to thepackage by the compression of the springs D2. Upon the completion of theengagement of the head with the cylindrical body the interrupted gear Pienters into mesh with the pinion P2, imparting rotary motion to theshaft PL and thereby driving all of the mechanism at the upper end ofthe machine. This will instantaneously start the members PlV in rotationcausing the engagement of the rolls P with the stops Q4 and in thefurther movement of the member P rocking the arms Q until arrested bythe stops Q5. This presses said rolls inward against the return bent'fiange of the chine-hoop and during the further movement of the memberP said flange will be rolled down against the cylindrical body.

During the operation just described the rotation of the annular member Pwill actuate the nail drivers X', one half of the number being firstmoved and at the completion of their movement the other half are oper-vated. The nails for this operation have previously been deposited in theradial slots X and are in the path of movement of the drivers whichforce them inward, the point first penetrating the body and then thechine-hoop and the head. The V shaped portion of the chine-hoop forms aguide for directing the point of the nail to the apex, thus insuringthat it will beproperly directed in entering the wood of the head. Inthe mean while the other movable parts of the nailing mechanism are inoperation, the member T being rotated to carry a series of nailspreviously deposited in the pocket '1" into reverse position and abovethe gate T3. The pockets W are also being carried by the movement of themember P and are out of registration with the nail conduits TL and justat the completion of the movement of said member P', the nails reversedby the member T will be above the gate T3, and the cam V will registerits notch V2 with the lug V3 permitting the spring V to snap open thegate T3. Thus just as the pockets W are brought into registration withthe conduits T 4 a set of nails is released by the gate T3 and fallthrough said conduits into the pockets W, from which they vdrop into theradial slots X also` in registration therewith. The nails thus depositedare in position for the succeeding operation. The nail assortingmechanism is also in operation during the movement just described, theshafts U imparting motion through the medium of the gear Wheels U2 tothe gear cranks R9, and the latter reciprocating the pitmans RS, crossbars R7 and fingers R3. The nails in contact with these fingers will befrictionally moved and will arrange themselves in parallelism' withinthe V shapedrecesses R', and during the successive reciprocations thelowermost nails in these recesses will drop into the slots R2. The headshowever, are too large to pass into the slots R2 and will be supportedupon the oblique flanges of the fingers R3. Thus the frictionalengagement between the heads and the lingers R3 will feed the nail inthe slot R2 downward through the slot beneath the lug R5 out from thehopper. As soon as the nail thus fed comes into full registration withthe slot in the guide RG the body willv drop through the slot and thenail assume a vertical position suspended by the head.

The capacity of the asserting mechanism for the nails is in excess ofthe demand of the machine and as a consequence the nails will accumulatein the guide ,R6 until the slots thereof are filled. When they reach apoint where the nail being drawn outward by the lingers R3 is stopped bya nail in the slotted guide R6 before the full length of the nail is inregistration with the slot the nail will be prevented from droppingthrough the slot, and consequently upon the return movement of thefingers R3 it will be moved back again; Thus the feeding of nails isstopped until removal of nails from the engagement therewith, of anabutment for said head, means for moving said support t to force thehead into the body, said abutment and movable support togetherconstituting a press, an annular member in iiXed relation torsaidabutment surrounding the headed end of the package, radial guides insaid annular member for nails, and means operating in sequence to theoperation of said press for forcing nails inwardin said guides throughsaid body and into the head.
